if the old node cannot be found the function returns false.
(php 4.3) this function replaces the child oldnode with the passed newnode, even if the new node already is a child of the domnode. if newnode was already inserted in the document it is first unlinked from its existing context. if the old node cannot be found the function returns false. if the replacement succeds the old node is returned. (this behaviour is according to the w3c specs).
l 'instruction if est une des plus importantes instructions de tous les langages, php inclus.
the if construct is one of the most important features of many languages, php included. it allows for conditional execution of code fragments. php의 if 문은 c와 비슷하다.:
ces expressions sont utilisées de manière courante dans les instructions conditionnelles, comme l 'instruction if.
the last example of expressions we'll deal with here is combined operator-assignment expressions. you already know that if you want to increment $a by 1, you can simply write '$a++' or '++$a'. but what if you want to add more than one to it, for instance 3? you could write '$a++' multiple times, but this is obviously not a very efficient or comfortable way. a much more common practice is to write '$a = $a + 3'. '$a + 3' evaluates to the value of $a plus 3, and is assigned back into $a, which results in incrementing $a by 3. in php, as in several other languages like c, you can write this in a shorter way, which with time would become clearer and quicker to understand as well. adding 3 to the current value of $a can be written '$a += 3'. this means exactly "take the value of $a, add 3 to it, and assign it back into $a". in addition to being shorter and clearer, this also results in faster execution. the value of '$a += 3', like the value of a regular assignment, is the assigned value. notice that it is not 3, but the combined value of $a plus 3 (this is the value that's assigned into $a). any two-place operator can be used in this operator-assignment mode, for example '$a -= 5' (subtract 5 from the value of $a), '$b *= 7' (multiply the value of $b by 7), etc.

l 'expression elseif est exécutée seulement si le if précédent et tout autre elseif précédent est évalués comme false, et que votre elseif est évalué à true.
the elseif statement is only executed if the preceding if expression and any preceding elseif expressions evaluated to false, and the current elseif expression evaluated to true.
